OK, will do.

VLBA started at 0355UT. GRB was at 0323UT - so we were 30 mins late. Oh well.

Adam says no detections and lots of RFI.

Additional info from Tony
No, we weren't observing. However, this was my first time processing one
and I wanted to make sure I had the extra time. I did need some extra time
to remove MK from observing by removing it from the observe.tx file, sending
it back out, and running queueVex to unqueue it from the observe.tx file on
the wide-band control computer.
Also, while KP was observing the DBEs weren't set up correctly, so apparently
there is no data from this site. Everything else should be OK, however.
